Complete quoting for parameters of some CMake commands

[elfring]

Some parameters (like "${CMAKE_SOURCE_DIR}/CMake" and "${CMAKE_CURRENT_BINARY_DIR}/reliability") are passed to CMake commands in your build scripts without enclosing them by quotation marks. I see that these places will result in build difficulties if the contents of the used variables will contain special characters like spaces.

I would recommend to apply advices from a Wiki article.
